Can anyone tell me what the purpose of thoe holes in the upper part of my frame are? I'm pretty sure all of the 90's had the hole.

Thats the theory, don't think we ever established that as fact.

My personal theory is that it promotes air circulation in the area under the tank cover to keep the coils from cooking. The holes in the frame don't look like enough area to feed the engine much. I also don't believe that they are there just for looks. The design is too involved for that - Metal tubes, rubber elbows on each end, ducts molded into the fairings.

All I know is that I've been running without mine for a couple of seasons with no ill effects, and no noticeable difference compared to when I did have them. -------------------- 1994 FZR 600 Streetfighter

The pretend ram air, funny when you pull the elbow out of the frame and see the <1" hole on the inside of the frame. I think it would provide some cooler air for under the tank cover. I took them off of my race bike with no issues, those metal tubes are heavy!

I use mine for connecting ratchet straps when I'm working on it and throwing them over the garage rafters as a safety catch. Saved my bike twice.

I had some plates waterjet out to fill said holes in... I am planning to smooth out my frame and then have it powdercoated.
